In this paper, we construct an elaborate general equilibrium model with a continuum of production fragments for an intermediate good, then embed it in a growth model to address the effects of global production fragmentation, vertical specialization and trade on growth and inequality for a small...

This paper studies structural change in production networks for intermediate inputs (input-output network) and new capital (investment network). For each network, we document a declining fraction of production by goods sectors and a rising fraction of production by services sectors. We develop a...

We develop a dynamic spatial model in which heterogeneous workers are imperfectly mobile and forward-looking and yet all structural fundamentals can be inverted without assuming that the economy is in a stationary spatial equilibrium. Exploiting this novel feature of the model, we show that the...

This paper examines how skill-biased growth can generate economic fragmentation (income dis-parities) that give rise to social fragmentation (the adoption of increasingly incompatible social identities and values), which generate political fragmentation (the adoption of increasingly incompatible...

During the last decades, the United States has applied increasingly high trade protection against China. We combine detailed information on US antidumping (AD) duties — the most widely used trade barrier — with US input-output data to study the effects of trade protection along supply...

Import regulations are globally the most prevalent form of intervention in international trade. The regulations should, under rules of the WTO, protect consumers and the environment but can be used to protect producers. We investigate the ambiguity of intent. We set out a model that when applied...

We study infant industry protection using a dynamic model in which the industry’s cost is initially higher than that of foreign competitors. The industry can stochastically lower its cost via learning by doing. Whether the industry has transitioned to low cost is private information. We use a...

Many of the exports of developing countries are channeled through global value chains (GVCs), which also act as conduits for new technologies. However, new capabilities and productive employment remain limited so far to a tiny sliver of globally integrated firms. GVCs and new technologies...

We study how technology adoption and changes in global value chain (GVC) integration jointly affect labor shares and business function specialization in a sample of 14 manufacturing industries in 14 European countries in 1999–2011. Our main contribution is to highlight the indirect effect of...
